The slope is 7

The y-intercept is 1

Step-by-step explanation:

First, we will make 7x - y = -1 fit into the formula format of y = mx + b, where:

7x - y = -1

-y = -7x - 1

y = 7x + 1

The slope is 7

The y-intercept is 1

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
